The move is a nod to players' pasts. According to MLB, players will be "sporting colorful, non-traditional uniforms featuring alternate designs inspired by youth-league uniforms....Additionally, during Players Weekend, the right sleeve of each player's jersey will feature a patch with a blank space for him to write the name of a person or organization that was instrumental to his development."

"These games will allow the players to thank those who were important in their lives while showcasing their personality in a fun way that fits baseball's community-driven focus," MLB Commissioner Rob Manfred added.
